On Amaryllis belladonna flowering, I've noticed that here in the Portland area it flowers only when growing up against warm walls or house foundations. I just moved mine to a west-facing wall of my brick house, under the eaves to protect them from too much winter wet. I put the Veltheimia bracteata there too -- grow or freeze, I don't care, but I'm tired of lugging its pot in and out. Alstroemeria isabellanae is in bud in that area, and some Iris unguicularis is scheduled to be moved there in fall. In central California, however, Amaryllis can flower in part shade. I remember them from my grandparents' farm near Lodi (Sacramento River delta), flowering on a partly shaded berm with assorted perennials; Grandmother called them "naked ladies," and giggled.
